How do I fit long title?
- matplotlib: Auto-wrapping text is the official answer from the
matplotlib
documentation- Review the Note for associated caveats.
- matplotlib: Text properties and layout are also useful
- It doesn't work to display an inline plot in Jupyter because of GitHub: Text wrapping doesn't seem to work in jupyter notebook #10869 unless you do this answer Matplotlib and Ipython-notebook: Displaying exactly the figure that will be saved
plt.savefig(...)
seems to work properly withwrap
import matplotlib.pyplot as plt
x = [1,2,3]
y = [4,5,6]
# initialization:
fig, axes = plt.subplots(figsize=(8.0, 5.0))
# title:
myTitle = "Some really really long long long title I really really need - and just can't - just can't - make it any - simply any - shorter - at all."
# lines:
axes.plot(x, y)
# set title
axes.set_title(myTitle, loc='center', wrap=True)
plt.show()
- The following also works
plt.figure(figsize=(8, 5))
# title:
myTitle = "Some really really long long long title I really really need - and just can't - just can't - make it any - simply any - shorter - at all."
# lines:
plt.plot(x, y)
# set title
plt.title(myTitle, loc='center', wrap=True)
plt.show()
Note
- The following way of adding an axes is deprecated
# lines:
fig.add_subplot(111).plot(x, y)
# title:
myTitle = "Some really really long long long title I really really need - and just can't - just can't - make it any - simply any - shorter - at all."
fig.add_subplot(111).set_title(myTitle, loc='center', wrap=True)
MatplotlibDeprecationWarning: Adding an axes using the same arguments as a previous axes currently reuses the earlier instance. In a future version, a new instance will always be created and returned. Meanwhile, this warning can be suppressed, and the future behavior ensured, by passing a unique label to each axes instance.
Here's what I've finally used:
#!/usr/bin/env python3
import matplotlib
from matplotlib import pyplot as plt
from textwrap import wrap
data = range(5)
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(data, data)
title = ax.set_title("\n".join(wrap("Some really really long long long title I really really need - and just can't - just can't - make it any - simply any - shorter - at all.", 60)))
fig.tight_layout()
title.set_y(1.05)
fig.subplots_adjust(top=0.8)
fig.savefig("1.png")
One way to do it is to simply change the font size of the title:
import pylab as plt
plt.rcParams["axes.titlesize"] = 8
myTitle = "Some really really long long long title I really really need - and just can't - just can't - make it any - simply any - shorter - at all."
plt.title(myTitle)
plt.show()
In the answer you linked are several other good solutions that involve adding newlines. There is even an automatic solution that resizes based off of the figure!
I preferred to adapt @Adobe's solution in this way:
plt.title("First Title\n%s" % "\n".join(wrap("Second Title", width=60)))
